Application filed June 1, 191%. Serial No. 8%,06 1.

referring more part-icnl mg, 5 represents the hub, iellv, and S, the tire or-ri To all w/m'm, Ii J may (10/1 cm lie it known that 1, Join l lianrrivnn, a citizen of the United States, residing at East- St, Louis, in the county of St. Clair and State oi Illinois. have invented a new in Spring-Tires, of which the following; a specification.

This invention relates to resilient tires, and more particularly to an improved spring tire.

One of the principal objects at the invention is to provide a spring tire includin'g an inner lixed rim, an outer movable rim connected to and spaced from the inner rim at a. plurality of points by circular band springs, and a cover or guard plate connected to the inner rim and adapted to prevent the entrance of dust or dirt between the rims.

Another object of the invention is to provide a tire of the class described including a mourble and immovable rim, and springs connecting them at a. plurality of points, the construction and arrangement of the springs being such as to equalize and distribute the tension incident to movement of one rim relatively to the other.

A further object of the invention is to rovide an improved tire of the class described which may be applied to wheels of standard. dimensions. or fitted especially to odd size wheels, and one which will be tremely simple, durable, eiiicieut in opera tion, and inexpensive to manufacture.

lVith these and other objects in view the invention resides in the construction, combination and arrangement of parts hereinafter more "fully described and claimed, and illustrated in the accompanying drawing, in which like characters of reference indicate like parts throughout the several figures, of which:

Figure 1 represents a side elevational view of a vehicle wheel. equip zed with my improved spring tire, a portion of the guard plate being broken away to reveal the rims. Fig. 2 represents a fragmentary side elevationzl view of the tire, the guard plate having been removed. Fig. 3 repre sents a transverse sectional view taken on the plane indicated by the line 3-3 of 2, the guard plate being sh own in place. and Fig. i represents a view similar to Fig taken on the plane indicated by the line H of Fig. 2.

the springs at one end are bent over as at '25 into engagement with lug 23 for maintaining the springs in place, the opposite ends 26 of the springs; lying flush with the surface of the inner rim. The sets of springs 24 are disposed in pairs, that is a solid portion 27 of one set which bridges the space 20 between the rims, di'sposed toward the solid portion 27 of the other member of the pair, this arrangement bein clearly indicated outer rim B is maintained in spaced relation 'with the inner rimby the sets of band springs, and it-is evident that upon move- ,ment of one' of the rims relatively to the other, tension incident to the movement will be taken up and distributed to the various sets of springs thus equalizing and distributing the tension through the circumference of,

the tire, thus insuring the liveliness and resiliency of the tire, and atthe same time lengthening the life of the springs by reason of the distribution of the tension.

.' ried by rim A and overhanging shoulder 29,

and a flange 30 carried by the cover or guard plate 0 and overhanging shoulder 28, said guard plate at its inner edge resting against flange 16 on rim A, and being connected to said rim by means of screws or other suitable fastening means 31, said guard plae or ring at its inner surface being provided with an"annular recess 32, which forms the flange 30 at the outer edge of the guard plate and in which groove the flange 28 is adapted to play. The guard plate maintains rim B against the flanges 11 and 12 carried by rim A, and in turn engages snugly against rim B so that no dust or dirt may enter between rims A, and B and ring C.

By this arrangement the 1,12o,esi

The spring. tire is "adapted to be placed upon a vehicle wheelwith the guard ring C on'the outside, 'so'that it may be easily removed for purposes of repairin and cleaning the tire, and when the guar rlng 1S removed the springs are exposed and are readily accessible forrenewal or repair. -Rim B .may if desired be provided with a rubber or other suitable tread in the formof a band 33. I

The number and width of the springs forming each set maybe varied at the option of the user, and although I have shown and described the sets as being substantiallyeircular, the shape .of the springs m'ay be varied, and such other changes in the construc- -tion, combination and arrangement of the.

parts'of the device maybe made as do not depart from the spirit of the invention and the scope of the appended claims.

I claim:

1. A spring tire including an innerrim, an outer rim,'said rims a t spaced intervals being recessed on one side to provide pairs of oppositely disposed lugs, band springs connecting said lugs, said springs at one end being bent upon the lugs carried byone of the rims, and at the, opposite end lying flush with the inner surface of the opposite rim,

means for limiting the movement of oneof the rims relativelyto the other, and means for preventing the entrance of dust between the rims.-

2. A springtire comprising a pair of spaced rims disposed one within the other and being of uniform internal and external diameter, said rims at spaced lntervals being provided withunlnterrupted arcuate recesses let into the sides of. the rims, band springsdisposed in the recesses and connecting the rims, a guard ring and a flange carried by one of the rims in spaced relation toeach other, and ooacting means betweenlthe ring and flange and the outer rim, for limiting the movement of the latter and preventing entrance of dust between the rims.
